Plurality voting in practice, with its tradeoffs and mitigations
A voter at the top marks the ballot and feeds into the engine, a container labeled "Single-winner voting method: Plurality voting (choose-one)" holding the ballot above the counting rule. The ballot lets the voter choose one candidate; the counting rule gives the win to the candidate with the most votes, majority or not. Below the engine, a box names the single winner: holds the most votes, not always more than half. To the right, a Tradeoffs box lists positives (simple to use, simple to administer, decisive in one round) and negatives (can elect a winner without majority support, splits similar candidates, rewards strategic voting, rewards base mobilization over broad appeal). Below it, a Mitigations box lists runoff elections, party primaries, candidate coordination or withdrawal, strategic voting, and viability signaling, noting none are guaranteed to fully remove vote-splitting.
